Title: Focusing ion beam device
Inventor: IWAMOTO HIROSHI
IPC: H01J37/22
Filed: 1993-04-21
Abstract: PURPOSE:To judge the correctness of the moving direction of a sample by moving the sample in the same line direction and the same row direction, scanningly radiating a focusing ion beam in the moving direction and the vertical direction, and monitoring periodicity of a secondary electron detecting signal. CONSTITUTION:A moving mechanism 10 is arranged under an ion beam radiating optical system, and an ion beam 8 focused by the optical system is radiated to a sample 9 held by the mechanism 10. When bits of the sample 9 are arranged regularly like a matrix, the sample 9 is moved in the row direction and the column direction, and the beam 8 is radiated while scanning repeatedly in the moving direction and the vertical direction. A secondary electron from the sample 9 is detected by a secondary electron detector 7, and a detecting signal is monitored on a display device 16. When the moving direction of the sample 9 is put in the row direction and the column direction, periodicity of the detecting signal is kept, but when the moving direction is deviated, periodicity of a change in the detecting signal is broken. Thereby, the correctness of the moving direction of the sample can be judged.

Abstract: PURPOSE:To round a groove corner by a method wherein a mask of an insulation film is formed on a semiconductor substrate, polycrystalline silicon is deposited on it, the polycrystalline silicon and the semiconductor substrate are continuously etched. CONSTITUTION:A mask of an insulation film 102 is formed on a semiconductor substrate 101, and polycrystalline silicon 103 is deposited. The polycrystalline silicon 103 and the semiconductor substrate 101 are continuously etched. The polycrystalline silicon 103 is thus etched first so that it remains as a side wall 104 on the side of silicon dioxide 102. If etching continues, the semiconductor substrate 101 is etched at a part where there is no polycrystalline silicon 103 so that etching of the semiconductor substrate 101 delays on the part of the side wall 104. Thus a groove corner can be rounded.
